if you do not want to use a delay with now Greenfoot.delay() try this: long starttime = System.currentTimeMillis(); act() { long endtime =System.currentTimeMillis(); if((endtime - starttime) < 200) { return; } starttime = System.currentTimeMillis(); .. rest of routine .. } this will give you at least a fifth of a second between acts for this actor.

This is pretty good. There are some technical issues, but it is entertaining. Can you make the ghost who were eaten have their eyes run back to the ghost box?

It is possible to land the flier on the 'Not Fair' level, I need to put a high score mention for anyone who was able to manage it.
